ABSTRACT
Past experiences indicate that industries such as petroleum and chemical that handle hazardous substances are more prone to major accidents. Maintenance can play a major role in the occurrence of such accidents. Some examples of the major accidents in the area of oil and gas industrial sector in which maintenance, directly or indirectly, has played a major role are Piper Alpha Disaster, Texas City Renery Explosion, Sodegaura Renery Disaster, and the Bhopal Gas Tragedy [1].
